runtests

这是一个同样来自贝尔实验室的和UNIX有着渊源的操作系统, 其简洁的设计和实现易于我们学习和理解

#
# Runs the test files that you'll find in this directory. You may want to change
# the definitions of PRINT and BINDIR. The default definition of BINDIR assumes
# the translators are installed in /usr/lbin/postscript, while PRINT just writes
# everything to stdout. Unrecognized options (ie. options other than -P and -B)
# are passed along to the translator.
#
# For example, if postio is installed in /usr/lbin/postscript, the following runs
# the dmd bitmap translator on the test file ./postdmd1 and sends the output to
# the printer attached to /dev/tty01.
#
#	runtests -P'/usr/lbin/postscript/postio -l /dev/tty01' -pland postdmd
